White chicks, no white parents

[Flockandfowl46]

I'm really inclined to say your roo did this simply because of all the diff characteristics of the hens to chicks

You may have hidden recessives in more than one of the flock

I figured as much. They do look pretty neat though and my husband loves them. That's what's important. Curious to find out what color eggs they'll lay.

My money is EE as a parent. I had some splash and a white bird hatch. 3 have dark legs and 2 have yellow. Im still unsure where the yellow came from. Possible moms were a splash EE and a buff Olive egger. But funny enough the buffs egg hatched a splash chick and the splashes egg hatched a black chick. Dad is blue.

Here are my youngsters.

So pretty! I think mine are EE and a bantam, my other roo is a cochin so it could go either way.
